A Transphase Eradication Rod, often shortened to TER, is a Goa'uld weapon used against the Reetou. The device is capable of bringing the invisible Reetou or any other cloaked entity into the visible field observed by humans. Once the Reetou is detected, the gun can fire a blast that blows the Reetou apart. The tok'ra have been able to steal some versions, and also use them against the Reetou rebels. The weapon was also the testbed for the Kull distruptor
